Abstract: A control apparatus for turning on and off an electrical load device which includes an enclosure having open top and bottom ends with a flexible member searingly connected inside the enclosure, the flexible member having top and bottom sides. A drive magnet is connected to the top side of the flexible member. The control apparatus further includes a mounting member carrying a switch and a pivotally mounted driven magnet. The pivotally mounted driven magnet and the drive magnet being positioned and arranged such that when fluid enters the open bottom end of the enclosure and applies pressure to the flexible member, a portion of the flexible member moves from a first position to a second position, carrying the drive magnet and bringing it into a repelling orientation with the driven magnet, which is repelled from the drive magnet and pivotally engages with the switch to operatively change the switch from a first state to a second state. The switch is operably connected to the electrical load device.

Abstract: A sump alarm system which includes a sensor, carried by a sensor housing, the sensor being operatively connected to an alarm circuit, carried in an alarm circuit enclosure, the alarm circuit configured to output an alarm signal when the sensor senses a predetermined alarm condition.

Abstract: A magnetically actuated float switch for turning on and off an electrical load device which includes a mounting member, a moveable bracket member which is attached to the mounting member and which is moveable between a first bracket position and a second bracket position by an external force. The moveable bracket member further has a first magnetic end and a second magnetic end which define a space therebetween. The first magnetic end and second magnetic end are oriented in a repelling arrangement. Insertion of a magnet in the space between the magnetic ends of the bracket results in the moveable bracket being moved from the first position to the second position. The moveable bracket member is operatively arranged to change the state of a switch between a first and second state. The switch is in turn operably arranged to change the state of an electrical load device between an on state and an off state.
